新增: 压缩失败降级前端透出与vite看门修复
- E2:LLM压缩失败走关键词摘要兜底时新发AiContextDegraded事件, 前端toast「上下文已降级」不再静默失忆(实证76730ce8 seq166 用户被迫原句重发);不发AiError防误判生成结束 - keyword_fallback_commit返回inserted供emit判定,双调用点 (LLM失败/provider重建失败)透出 - vite watch忽略target/:cargo编译写.o触发EBUSY杀掉dev进程 验收:cargo check 0 error;keyword_fallback 3 passed;vue-tsc EXIT 0
